quadN rate freq a b c xi
quadL rate freq a b c xi
quadC rate freq a b c xi

freq    - iteration frequency in Hertz
a, b, c - equation variables
xi      - initial value of x

General quadratic map chaotic generator.  Non-, linear- and cubic-
interpolating sound generators based on the difference equation:
xn+1 = axn2 + bxn + c
